Is there any way I can call the functions in a dll file created in VB in
a java program.
If there is, how can I do it. Do I have to do it in the same way as in VB,
by declaring it first and calling the necessary fucntions.
Thanks in advance.

Re: Call functions from VB Dll

Yes. You need to write a class that contains native methods that wrap the
functions from the DLL. To do that you need to do some JNI programming. If
you don't want to do that (I certainly didn't), then go to IBM Alphaworks
(http://www.alphaworks.ibm.com/tech), select Java in the left frame, and
look for Bridge2Java, a product which will generate the class for you.

Thanks Paul.
I downloaded the program and did the set up.
But I was not a able to generate the file.

What should we enter in "Type Library Name". Isn't there where we should
enter the name of our dll file. I entered the dll file there. But the error
was " Unable to process the library type data".
Please help.

And there's a place on the site you got that from where you can ask for help
